Areas of Interest

Analytical and Electrochemistry

 

Research in the Ji Group

Research in Ji’s Group is focused on several areas: (1) electrochemical synthesis by using various Schiff base catalysts with study on the reaction mechanisms; (2) modification of electrode surface with novel catalysts for the development of chemical sensors; (3) synthesis of functionalized gold nanoparticles for electrochemical catalysis; (4) measurement of environmentally important parameters such as Henry’s law constants.

In the laboratory, the students will have opportunities to learn various techniques in analytical, electrochemistry, and organic synthesis. They would also acquire skills in purification, identification, and quantitation of chemical products by using different instruments including GC, GC-MS, LC, LC-MS, NMR, and UV-Vis.
